My guess is that you are not hearing the "pump" (compressor) but are hearing the evap fan. Check your relay/overload (its attached to the compressor in back). If there was a power surge, it could have died. Haven't worked on a Dansby, so I can't give you specifics.

You might look through the refrigerator forum for better info. That's where AJ will move this to in a bit.

I do danby warranty work in Canada ,if its under warranty and has a sealed system issue the unit gets replaced by Danby .Out of warranty parts are not available ,I suppose you could use generic parts but its not worth it .Basically throw away if they break because they are cheap to buy in yhe first place .
